bson_string_truncate - Man Page

void
bson_string_truncate (bson_string_t *string, uint32_t len);

• string: A bson_string_t <>.
• len: The new length of the string, excluding the trailing \0.

Truncates the string so that it is len bytes in length. This must be smaller or equal to the current length of the string.

A \0 byte will be placed where the end of the string occurs.

Warning:

This function is oblivious to UTF-8 structure. If truncation occurs in the middle of a UTF-8 byte sequence, the resulting bson_string_t <> will contain invalid UTF-8.

Warning:

The length of the resulting string (including the NULL terminator) MUST NOT exceed UINT32_MAX.
